Be it known that we, GEORGE M. BEILL and JAMEs RAwLE, ofthe city andcounty of Philadelphia, and State of Pennsylvania, have invented anImprovement in Carflrucks for Cable Railways, of which the following isa specification.

Our invention has reference to car-trucks especially adapted to cablerailways 5 and it consists in certain improvements fully set forth inthe following speciiication and shown in the accompanying drawings,which form part thereof.

In cable-railway cars it has been customary to use simply a four-wheeltruck rigidly' con` nected to the car-body, and from the center of whichthe gripping apparatus depended, having suitable provision for lateral1novement in going around curves, in which case the grip proper would bethrown nearer to one side than to the other, or in the case of largecars-such as used upon the Brooklyn bridge-two ordinary pivotedrailway-trucks are used, and the gripping device attached to the body ofthe car midway between them. It has been found that rigid trucks areobjectionable,owing tothe fact that the axles must be close together topass around short curvessuch as found in street-railways-and with thelong cars now constructed i'or cable railways it is found that whenfully loaded the carbody docs not rest properly upon the truck, but inmost eases tends to raise the forward wheels, endangering the car byderailment and breakage ol` the grip; and in the case ofthedouble-pivoted truclccars, with the grip attached to the body, itwould be impossible to use them for any purpose excepting such roads asthose in which the cable was supported above the ground and in which nosharp curves were encountered; but this form of construction is totallyincapable of use on street cable railways as now constructed.

The object of our invention is to enable a long ear having two pivotedtrucks to be used upon the cable-railway systems as at present adoptedin street-railways,by providing a truck, preferably at the forward endof the car, whose center shall be provided with a space suiiciently opento receive the cable-grip,yvhieh is suspended from the center thereof,or below the pivotal connection with its pivotal point.

the car-body. To accomplish this result and yet employ grips proved bypractice to be the best adapted to cable railways, it becomes necessaryto eliminate entirely the lower cross-timber supporting the car-springs,the links usedto supportthe said timber and their appendages, and alsoto sever the bolster and provide suitable means to support the endsthereof and receive the pivot-shoe at tached to the body of the car, soas to enable the gripping devices to besuitahly located and attached inthe center of the truck or beneath l-By this means, no mattei" what thelength oi the car may be, it can easily be propelled by a cable arrangedin an underground eonduit, as in this case the grip would have but veryslight lateral motion in passing around curves, which lateral motionwould be entirely imlependeut of the length oi' the car.

In the drawings, Figure l isa sectional elevation on line a .r ot' acar-truck for cable railways embodying our invention. Fig. 2is a planview of saine with the frame-work of the car-body indicated in dottedlines; and Fig." 3 is a side elevation ol' a ear, showiugthe arrangementof the trucks thereunder.

A represents the truck, and B the canbody. The truck A is provided withthe usual trussing or brace-frame, G, provided with the journal-boxes inwhich the axles and wheels D are journaled. These trusses are alsoprovided with guidevfraxnes F, wh ich are made U shaped, and are adaptedto receive the ends ol' the bol ster G, and also support thebolsterspriugs W', upon which the weight of the ear is received, thebolster heilig Ylrec to move vertically and longitudinally in saidguides. The longitudinal thrust due to the lateral swinging of theear-body when passing around the curves is taken up by the springs f,arranged between the guides F and suitable thrust-blocks attached to thebolster ends, which springs are preferably arranged upon the inner sideof the trusses. These trusses are secured together by the cross-bars E,riveted to the lower tierods of the said trusses, thus uniting the partsinto a compact truck. rlhe bolster Ghas a eenA tral portion cutaway andthe two ends united by the elliptical-shaped casting or forging H,provided with socket portions M, in which the wooden end sections of theholster are secured. This casting H is provided with the segmental IOO 'them.

guides I, preferabl y grooved,as shown, and into which the curved partsK of the pivot-shoe J project, which shoe is fastened to the car-body.By this means the truck may turn about the shoe J at an angle equal tothat contained between the vertical line through Fig. 2 and the dottedline y y, which is sufficient for all curves. The forward and rear endsof the casting H may be raised, as at 71 so as to clear the gripmechanism and allow of its lateral movement as well as the verticalmovement of the bolster and its frame H. This allows of all themovementnecessary for different loads which the car might be made to carry, aswell as such movements as would be produced in running around curves,without danger of interfering with the grip.

R is the grip, and its upper portion is provided with holes in-which thepins p pass to secure it to the lateral slide-bars I?, guided in guidesO, which are secured upon longitudinal bars N, fastened to cross-bars E,or said guides may be directly fastened to said crossbars. Any othermethod of attaching the grip to the truck may be employed; but thismethod is that found most practical, as while it embodies rigidity itadmits of all necessary adjustability.

The upper portion of the grip is provided with the operating-bar S andthe return-bar T, around which the spring L is placed, and all of theseparts project up into the casting H, which is properly proportioned toreceive If desired, both trucks may be provided with gripping devices ofthis nature; but it is considered unnecessary, as that on the forwardtruck will suffice.

We do not limit ourselves tothe exact shape of the casting or forging H,as it may be modified in various ways without departing from ourinvention.

Of course it is understood that the shape and construction of the gripshown maybe modified or changed as desired, as this in vention isadapted to any of the grips now in use.

Having now described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

l. rlhe combination of a car-body with pivoted four-wheeled truckprovided with a bolster having an opening within the pivot thereof, andagrippiug device for a cable railway, located under the pivot-center andeX- tending up within the opening in the bolster, substantially as andfor the purpose specified.

2. A truck having a divided bolster, the two end sections thereof beingunited by an annular or ring shaped casting,which also acts as the pivotfor the car-body, substantially as and for the purpose specified.

3. A truck having a divided bolster, the two end sections thereof beingunited by an annular or ring-shaped casting, which also acts as thepivot for the car-body, in combination with a gripping device for cablerailways supported within said annular casting and between the twosections of the bolster, substantially as and for the purpose specified.

4. In a car-truck, the axles and side trusses or bracing provided withsuitable vertical bolster-guides, in combination with the bolsteradapted to support the car body and move vertically and longitudinallyin said guides, springs supported upon said side trusses and arrangedunder said bolster, and auxiliary springs arranged between the bolsterand guides or trusses to receive the longitudinal thrust of the bolsterdue to the lateral swinging of the car-body in going around curves,whereby the desired results are attained, and the truck under thebolster is left clear and unobstructed, cross-bars connecting the lowerparts of said side trusses, and gripping devices for cable railwayssupported upon said crossbars and under the pivot of the truck,substantially as and for the purpose specified.

5. The combination, in a car-truck, ofthe bolster G, having its centercut away and its ends united by an annular casting or forging, H,provided with pivot-bearin gs Lwith the pivotshoe J, substantially asand for the purpose specified.

6. In a car-truck, the bolster G, having its center cut away and itsends united by an aunular casting or forging, H, havingits front andrear parts, h, raised, and provided with the pivot-bearings I, incombination with a gripping device for a cable railway supported by saidtruck and extended up within said annular casting, substantially as andfor the purpose specified.

7. The .combination of side trusses, C, axles and wheels D, with cross'-bars E, connecting the said trusses, guides E in said trusses, springsWV in said guides and under the bolster, divided bolster G, annularcasting or forging H, uniting the bolster ends and having the hearingsI, pivot-shoe J, carried by the car-body, slide-bars I), carried inguides upon bars N, and a gripping device for cable railways carriedupon said slide bars,substantiall y as and for the purpose specified.

8. A bolster for a car-truck, consisting of the two separated or endsections, G G, of wood, in combination with an annular casting orforging of metal provided with the pivotbearings and uniting the endsections, substantially as and for the purpose specified.

9. The bolster for a car-truck, consisting` of the end sections, GG, ofwood, in combination with the annular casting or forging H, havingA theraised part h, and sectional pivot-bearings I, substantially as shown.

In testimony` of which invention we hereunto set our hands.
